Dj. Mindiola et al., Dinitrogen cleavage stemming from a heterodinuclear niobium/molybdenum N-2complex: New nitridoniobium systems including a niobazene cyclic trimer, ORGANOMETAL, 19(9), 2000, pp. 1622-1624
Preparation of the terminal nitrido anion (-)[NNb(N[Pr-i]Ar)(3)] and the ni
obazene trimer {(mu-N)Nb-(N[Pr-i]Ar)(2)}(3) (Pr-i = CH(CH3)(2) or CH(CD3)(2
), Ar = 3,5-C6H3Me2) entails cooperative splitting of dinitrogen upon reduc
tion of the heterobimetallic paramagnetic dinitrogen complex (Ar[R]N)(3)Mo(
mu-N-2)Nb(N[Pr-i]Ar)(3) (R = Bu-t or C(CD3)(2) CH3).
